CHICAGO (AP) - Chicago teachers are suspending a seven-day strike in the nation's third-largest city, a move that will send thousands of students back to classrooms.

The union's House of Delegates voted Tuesday to suspend the strike after learning details of a tentative contract agreement.

A proposed settlement was presented to delegates during the weekend. Sticking points included teacher evaluations and job security, provisions at the core of a debate about the future of public education across the nation.

The union delayed its vote to give teachers more time to assess the contract they'll vote on in the coming weeks.

Mayor Rahm Emanuel had pushed for a quick resolution as parents found alternatives for about 350,000 students. He even went to court to try to force teachers back to class.
